When does quoting become troubleshooting

The difference between the two is information. An estimate/quote is given when a know quantity of time and materials can be written up to complete a project. For instance… installing a light fixture, ceiling fan, or other item. A troubleshoot is when a problem exists that must be found before an estimate can be given. Since the problem must be found, we are not sure how long it will take to find or the materials that will be needed to make the repair. Troubleshooting is not free and usually takes between 1 and 3 hours. Once the problem has been found we can give a quote to make the needed repairs.
